Abstract
INTRODUCTION Previous randomised controlled trials (RCTs) suggest antibiotics for treating episodes of asthma-like symptoms in preschool children. Further, high-dose vitamin D supplementation has been shown to reduce the rate of asthma exacerbations among adults with asthma, while RCTs in preschool children are lacking. The aims of this combined RCT are to evaluate treatment effect of azithromycin on episode duration and the preventive effect of high-dose vitamin D supplementation on subsequent episodes of asthma-like symptoms among hospitalised preschoolers. METHODS AND ANALYSIS Eligible participants, 1-5 years old children with a history of recurrent asthma-like symptoms hospitalised due to an acute episode, will be randomly allocated 1:1 to azithromycin (10 mg/kg/day) or placebo for 3 days (n=250). Further, independent of the azithromycin intervention participants will be randomly allocated 1:1 to high-dose vitamin D (2000 IU/day+ standard dose 400 IU/day) or standard dose (400 IU/day) for 1 year (n=320). Participants are monitored with electronic diaries for asthma-like symptoms, asthma medication, adverse events and sick-leave. The primary outcome for the azithromycin intervention is duration of asthma-like symptoms after treatment. Secondary outcomes include duration of hospitalisation and antiasthmatic treatment. The primary outcome for the vitamin D intervention is the number of exacerbations during the treatment period. Secondary outcomes include time to first exacerbation, symptom burden, asthma medication and safety. ETHICS AND DISSEMINATION The RCTs are approved by the Danish local ethical committee and conducted in accordance with the guiding principles of the Declaration of Helsinki. The Danish Medicines Agency has approved the azithromycin RCT, which is monitored by the local Unit for Good Clinical Practice. The vitamin D RCT has been reviewed and is not considered a medical intervention. Results will be published in peer-reviewed journals and presented at international conferences. TRIAL REGISTRATION NUMBERS NCT05028153, NCT05043116.

Abstract
Background Studies in low-income countries have shown that among Bacille Calmette-Guérin (BCG) vaccinated children, those who develop a BCG-scar have significantly better survival than those who do not develop a scar. In a Danish multicenter randomized clinical trial we assessed determinants for developing a BCG-scar and for BCG scar size following neonatal BCG vaccination. Methods At three Danish hospitals, newborns were randomized 1:1 to BCG vaccination or no BCG vaccination. The infants were invited for a clinical examination at the ages of 3 and 13 months. At 13 months, the scar site was inspected and scar size measured. We investigated three groups of determinants; external, parental, and individual-level determinants on relative scar prevalence and differences in median scar sizes. Results Among 2118 BCG vaccinated infants, 2039 (96 %) were examined at 13 months; 1857 of these (91 %) had developed a BCG-scar. Compared with Copenhagen University Hospital, Hvidovre (85 %), Copenhagen University Hospital, Rigshospitalet had a scar prevalence of 95 % (adjusted Prevalence ratio (aPR) = 1.24 [CI 95 %: 1.18 to 1.30]); it was 93 % at Kolding Hospital (aPR 1.27 [CI 95 %: 1.19 to 1.35]). Increasing vaccine experience was positively associated with developing a scar and with scar size. Conclusion Across multiple potential determinants of BCG scaring and size, logistical factors dominated. The results support that injection technique is an important determinant of developing a scar. Given the strong link between having a BCG scar and subsequent health, improved BCG vaccination technique could play a major role for child health.

Abstract
BACKGROUND The Bacille Calmette-Guérin (BCG) vaccine against tuberculosis (TB) may have beneficial non-specific effects (NSEs) beyond the protection against TB. This may be related to modifications of the innate immune system. We investigated the effect of BCG at birth on differential white blood cell (WBC) count in healthy, Danish infants. METHOD The Danish Calmette Study randomised newborns to BCG at birth (Danish strain 1331, Statens Serum Institut) or no intervention. A sub-group of infants had blood samples collected 4 days after randomisation (n = 161), and at age 3 months (n = 152) and 13 months (n = 300). We evaluated the effect of BCG on WBC differential count (total leucocytes, lymphocytes, monocytes, eosinophil, neutrophil and basophil granulocytes (109 cells/L)) measured in peripheral blood. RESULTS Overall, we found no effect of BCG on differential WBC counts at any time point. CONCLUSION BCG at birth did not affect WBC count in our cohort of healthy, Danish infants.

Abstract
Background The Bacillus Calmette-Guérin vaccine (BCG) against tuberculosis is administered intradermally, and vaccination is often followed by a scar at the injection site. Among BCG-vaccinated individuals, having a scar has been associated with lower mortality. We aimed to examine the impact of vaccination technique for scarring in a high income setting, by assessing the associations between the post injection reaction, the wheal size, and the probability of developing a scar, and scar size. Methods This study was nested within a clinical multicenter study randomizing 4262 infants to either BCG vaccination (BCG 1331 SSI) or no intervention. In this substudy, including 492 vaccinated infants, the immediate post BCG vaccination reaction was registered as either wheal (a raised, blanched papule at the injection site), bulge (a palpable element at the injection site), or no reaction. The presence or absence of a BCG scar and the size the scar was measured at 13 months of age. Results Of 492 infants included, 87% had a wheal after vaccination, 11% had a bulge, and 2% had no reaction. The mean wheal size was 3.8 mm (95% confidence interval 3.7–3.9). Overall, 95% (442/466, 26 lost to follow-up) of BCG-vaccinated infants had a scar at 13 months of age. In infants with a wheal, the probability of developing a scar was 96%, declining to 87% in the case of a bulge, and to 56% in the case of no reaction (p for same probability = 0.03). Wheal size was positively correlated with the probability of getting a scar and scar size. Conclusion Scarring after BCG vaccination has been associated with lower infant mortality. In a high-income setting, we found that correct injection technique is highly important for the development of a BCG scar and that registration of the category of BCG skin reaction (as wheal, bulge, or no reaction) may be used to identify infants at risk of scar failure. Finally, the wheal size was positively associated with both the probability of getting a scar and scar size. Trial registration The study was registered at www.ClinicalTrials.gov with trial registration number NCT01694108.

Abstract
AIMS The glycolysis-derived metabolite methylglyoxal has been linked to clinical microvascular complications, including diabetic nephropathy. We aimed to further investigate the hypothesis that methylglyoxal is involved in decline in renal function by assessing the associations between measures of renal function during a 6-year follow-up in 1481 people with screen-detected Type 2 diabetes, as part of the Danish arm of the ADDITION-Europe trial (ADDITION-DK). METHODS Biobank serum samples collected at ADDITION-DK baseline (2001-2006) and follow-up (2009-2010) were used in the current analysis of methylglyoxal. We assessed cross-sectional baseline and longitudinal associations between methylglyoxal and urinary albumin-to-creatinine ratio (ACR) or estimated GFR (eGFR), and between methylglyoxal and categories of albuminuria or reduced eGFR. RESULTS Baseline methylglyoxal was positively associated with ACR at baseline (12% higher ACR per doubling in methylglyoxal levels), and change in methylglyoxal during 6 years of follow-up was inversely associated with change in eGFR (-1.6 ml/min/1.73 m2 per doubling in methylglyoxal change), in models adjusted for age, sex, HbA1c , systolic blood pressure, anti-hypertensive treatment, LDL-cholesterol, lipid-lowering treatment, C-reactive protein and smoking. CONCLUSIONS In a population of people with screen-detected Type 2 diabetes, we observed associations between methylglyoxal and markers of renal function: 6-year change in methylglyoxal was inversely associated with 6-year change in eGFR. Also, methylglyoxal at baseline was positively associated with ACR at baseline. Our study lends further support to a role for methylglyoxal in the pathogenesis of diabetic nephropathy.

Abstract
AIMS Cardiovascular autonomic neuropathy and diabetic peripheral neuropathy are common diabetic complications and independent predictors of cardiovascular disease. The glucose metabolite methylglyoxal has been suggested to play a causal role in the pathogeneses of diabetic peripheral neuropathy and possibly diabetic cardiovascular autonomic neuropathy. The aim of this study was to investigate the cross-sectional association between serum methylglyoxal and diabetic peripheral neuropathy and cardiovascular autonomic neuropathy in a subset of patients in the ADDITION-Denmark study with short-term screen-detected Type 2 diabetes (duration ~ 5.8 years). METHODS The patients were well controlled with regard to HbA(1c), lipids and blood pressure. Cardiovascular autonomic neuropathy was assessed by measures of resting heart rate variability and cardiovascular autonomic reflex tests. Diabetic peripheral neuropathy was assessed by vibration detection threshold (n = 319), 10 g monofilament (n = 543) and the Michigan Neuropathy Screening Instrument questionnaire (n = 966). Painful diabetic neuropathy was assessed using the Brief Pain Inventory short form (n = 882). RESULTS No associations between methylglyoxal and cardiovascular autonomic reflex tests or any measures of diabetic peripheral neuropathy or painful diabetic neuropathy were observed. However, a positive association between methylglyoxal and several heart rate variability indices was observed, although these associations were not statistically significant when corrected for multiple testing. CONCLUSION Serum methylglyoxal is not associated with cardiovascular autonomic neuropathy, diabetic peripheral neuropathy or painful diabetic neuropathy in this cohort of well-treated patients with short-term diabetes.

Abstract
AIMS/HYPOTHESIS Recent evidence links the soluble urokinase plasminogen activator receptor (suPAR), a stable biomarker of systemic immune activation, to several chronic diseases, including type 2 diabetes. suPAR is also associated with adiposity and smoking. We hypothesised that this biomarker would be linked to incident type 2 diabetes in individuals with impaired glucose regulation and that this association would be modified by smoking and body weight status. METHODS The study included 1,933 participants with impaired glucose regulation, who were drawn from the Danish arm of the Anglo-Danish-Dutch Study of Intensive Treatment in People with Screen-Detected Diabetes in Primary Care (ADDITION) and for whom data on suPAR, BMI and smoking were available. Logistic regression analysis was used to estimate the odds for incident type 2 diabetes per twofold increase in suPAR levels. Interactions between both smoking and body weight status and suPAR were tested. RESULTS During a 3-year follow-up (599 incident diabetes cases), there was a 48% overall increase in the odds of developing type 2 diabetes per twofold increase in suPAR (p = 0.006). This association was modified by body weight status in overweight, but not in obese individuals (OR 2.36, 95% CI 1.48, 3.76 in overweight group), and by smoking status (OR 2.05, 95% CI 1.20, 3.51 in non-smokers). After adjustment for other diabetes risk factors, the association between suPAR and type 2 diabetes was attenuated in the whole sample and among non-smokers, but remained robust among overweight participants. CONCLUSIONS/INTERPRETATION suPAR may be a good novel biomarker for systemic sub-clinical inflammation and immune activation linked to incident type 2 diabetes risk in overweight individuals and non-smokers. The observed interactions with adiposity and smoking should be investigated further.

Abstract
SUMMARY BACKGROUND Infusion of artificial colloids such as hydroxyethyl starch (HES) induces coagulopathy to a greater extent than simple dilution. Several studies have suggested that the coagulopathy could be corrected by substitution with a fibrinogen concentrate. OBJECTIVES The aims of the present prospective, randomized, placebo-controlled trial were to investigate the hemostatic effect of a fibrinogen concentrate after coagulopathy induced by hydroxyethyl starch in patients experiencing sudden excessive bleeding during elective cystectomy. METHODS Twenty patients were included. Blood loss was substituted 1:1 with HES 130/0.4. At a dilution level of 30%, patients were randomly selected for intra-operative administration of a fibrinogen concentrate or placebo. The primary endpoint was maximum clot firmness (MCF), as assessed by thromboelastometry. Secondary endpoints were blood loss and transfusion requirements, other thromboelastometry parameters, thrombin generation and platelet function. RESULTS Whole-blood MCF was significantly reduced after 30% dilution in vivo with HES. The placebo resulted in a further decline of the MCF, whereas randomized administration of fibrinogen significantly increased the MCF. Furthermore, only 2 out of 10 patients randomly chosen to receive fibrinogen substitution required postoperative red blood cell transfusions, compared with 8 out of 10 in the placebo group (P = 0.023). Platelet function and thrombin generation were reduced after 30% hemodilution in vivo, and fibrinogen administration caused no significant changes. CONCLUSIONS During cystectomy, fluid resuscitation with HES 130/0.4 during sudden excessive bleeding induces coagulopathy that shows reduced whole-blood maximum clot firmness. Randomized administration of fibrinogen concentrate significantly improved maximum clot firmness and reduced the requirement for postoperative transfusion.

Abstract
Following an acute myocardial infarction (AMI) there is immediate deterioration of contractility in the infarcted left ventricular (LV) wall. This can be followed by regional dilation (expansion) as well as global remodeling. We examined 35 consecutive patients--with no history of myocardial ischemia--who were admitted to hospital within 3 hours after initial symptoms and with ST-segment changes on an electrocardiogram consistent with transmural ischemia. Echocardiography was performed at admission, and at 6 hours, 12 hours, 24 hours, 3 days, and 6 days after onset of the AMI. Within 3 hours after onset of symptoms an increase in both end-diastolic volume index (EDVI) and end-systolic volume index (ESVI) was found in both anterior and inferior infarcts when compared with healthy controls (mean +/- SD EDVI: 99 +/- 13 ml/m2 [anterior], 69 +/- 17 ml/m2 [inferior], 51 +/- 15 ml/m2 [controls], p < or = 0.00001; ESVI: 62 +/- 12 ml/m2 [anterior], 38 +/- 11 ml/m2 [inferior], 17 +/- 6 ml/m2 [controls], p < or = 0.00001). At all points in time, volumes were larger in anterior infarcts than in inferior infarcts (p < 0.05). The volumes did not change during the 6 days (p > 0.1). Thus, major LV dilation is present within 3 hours after onset of symptoms of first AMI. The dilation is more pronounced in anterior versus inferior infarcts. From 3 hours until day 6 no further changes in LV volumes occurred.

Abstract
Ten patients without cardiac disease or pulmonary dysfunction were exposed to an inspiratory pressure of 0, 10 and 20 cmH2O, in random order, via a nasal mask during the first postoperative day after scoliotic surgery. These patients were in the supine position, and a BiPAP respiratory assist device was used. Arterial oxygen saturation increased significantly during the application of 10 and 20 cmH2O, while none of the haemodynamic parameters (cardiac output, central venous pressure, right ventricular ejection fraction, right ventricular end diastolic volume, mean pulmonary artery pressure, pulmonary artery wedge pressure, pulmonary vascular resistance) changed significantly, contrary to the findings during continuous positive airways pressure treatment. In addition, the BiPAP was generally well tolerated by the patients.

Abstract
In 30 patients subjected to craniotomy, subdural pressure was measured with a 22G/0.8 mm Venflon cannula connected to a pressure transducer system. The measurements were performed after removal of the bone flap and just before opening of the dura. The subdural pressure was correlated with the tactile estimation of dural tension and the tendency to brain herniation after opening the dura. The results indicate that generally there is a poor agreement between the tactile feeling of dural tension and subdural pressure. Thus, in some patients with a relatively high dural pressure the dural tension was evaluated as relaxed. At subdural pressure below 6 mmHg brain herniation never occurred. On the other hand, at tensions over 7 mmHg some brain herniation occurred in all patients, and at tension over 11 mmHg pronounced brain herniation occurred. The method of subdural pressure used in this study is simple, the duration of the measurement is less than 1 min. It is concluded that measurement of subdural pressure before opening of the dura gives important information.

Abstract
Twenty-one patients with hydronephrosis mean age 37 years (11-72) were operated using Anderson-Hynes pyeloplasty, without routine use of a nephrostomy catheter. One patient developed urinary leakage postoperatively, which ceased after insertion of a ureteric catheter. Follow-up assessment was performed after a mean observation time of 85 months (44-142). Clinical examination, laboratory investigations, urography and renography were performed preoperatively and at follow-up. No signs of stones or stenosis in the pelvis were found. The patients operated upon before the age of 30 showed improved postoperative renal function. All patients had symptoms preoperatively, but only one had symptoms postoperatively. It can be concluded that the results of surgical intervention in hydronephrosis are excellent, especially in patients below 30 years.

Abstract
"Corkscrew oesophagus" is characterised on the basis of two case reports and attention is drawn to thoracic pain of oesophageal origin. Corkscrew oesophagus is a radiological diagnosis and is characterised by twisted segments in the distal third of the oesophagus. The condition can sometimes be demonstrated endoscopically and it is due to a basic disturbance in the motility of the oesophagus. Painful conditions in the oesophagus are most frequently caused by gastro-oesophageal reflux or disturbances in motility and the latter is frequently complicated by reflux oesophagitis. Pain of oesophageal origin is frequently a diagnosis by exclusion and requires exclusion of ischaemic heart disease. The initial treatment should be directed to the reflux oesophagitis. The diagnosis and information about the origin of the pain and the benign course of the condition will calm the majority of the patients and remove their fear of a possible fatal heart disease.

Abstract
The biocompatibility of cuprophanc haemodialyser membranes was investigated during two haemodialysis sessions in ten stable male chronic haemodialysis patients. In one session heparin was given intravenously, while it was given in the arterial line in the other session, using the same amount of heparin and the same filter. Biocompatibility was determined by measuring platelet and leukocyte counts, plasma beta-thromboglobulin, C3d, elastase, and lactoferrin in the arterial line at 0, 10, and 90 min of dialysis, and in the venous line at 10 and 90 min. Adequate anticoagulation was ensured by determining activated partial thromboplastin time. Platelet counts remained unchanged, whereas leukocyte counts transitorily decreased during dialysis. Plasma beta-thromboglobulin, C3d, elastase, and lactoferrin increased during haemodialysis, but no differences could be found between the two methods of heparinisation. The activation of complement, platelets, and leukocytes seemed to be independent of the mode of heparinisation.

Abstract
The benefits in the management of pathological fractures by internal fixation are well recognized. However, failures in bone or metal can occur where there is a large amount of bone destruction. Seven of 69 pathological fractures in our series were treated by internal fixation with adjunctive use of methylmethacrylate without failure. This allowed for secure fixation in fractures with large amounts of bone destruction, thus decreasing the patient's pain and allowing earlier mobilization. Neither the effects of radiotherapy on bone involved with neoplasm nor methylmethacrylate are altered when radiotherapy is used after internal fixation and adjunctive use of methylmethacrylate. We believe that an aggressive program of stabilization of these fractures or fixation before actual fracture provides significant patient benefits including reduction of pain, decreased length of hospital stay, reduction of financial expense, and return to as near normal function as possible.
